Those bags do look interesting! Will you be hunting from a camp or backpacking in?MM southern colorado 10k to 11k been looking at the duel temp eureka bags
We dont know if we going or not its just up in the air for now an we going to back pack in or take the horses my cuz knee is in bad shape an Im not packing everything by myself when we hunt in Oct I use a -35 deg cabelas 3D sleeping bag just dont want to take to much or to littleI dont know the temp rating but I have the army sleep system which is a lighter bag, a heavier bag, and a bivy bag that all snap together. When I backpacked CO high country in sept I used the light bag and it was warm enough but I wouldnt say it was alot extra. If I think the light bag wont be enough I take an army poncho liner, its light and adds quite a bit warmth. Backpacking I prefer to have a lighter bag and take some heavier base layers so I can wear them sleeping and hunting if it gets colder then expected.
Id say I may sleep cold sheephunter I never sweat sleepingdepends on whether you're a "cold sleeper" or a "warm sleeper". Even in mid September I'm most comfortable in the high country with a 0 degree bag. I almost always wake up cold in the middle of the night. My theory is that my body runs out of fuel in the wee hours of the morning so I have to get up and have a snack to keep the inner fire going. I've also been known to keep a pot of water ready to heat (at my age I have to get up in the middle of the night to pee anyway), and put the warm water in a nalgene bottle and put it down in my bag to help keep warm til morning.
